Many people believe that a person's sexual orientation is genetic. Given the widespread prejudice against, and hatred of, homosexuals in many societies, it seems likely that many parents will be interested in using genetic technologies to prevent the birth of children who will not be heterosexual. This paper considers the moral and legal implications of such procedures (whether or not they would work). It is argued that the availability of procedures to select the sexual orientation of children would contribute to (...) discrimination and prejudice against lesbians, gay men and bisexuals and, more generally, undermine the maintenance of a just society. These effects carry significant weight in determining whether genetic technologies should be developed and whether their use is, or should be, legally permissible and morally acceptable. (shrink)

Research into the genetic component of some complex behaviors often causes controversy, depending on the social meaning and significance of the behavior under study. Research into sexual orientation—simplistically referred to as “gay gene” research—is an example of research that provokes intense controversy. This research is worrisome for many reasons, including the fact that it has been used to harm lesbians and gay men. Many homosexual people have been forced to undergo “treatments” to change their sexual orientation. Others chose to undergo (...) them to escape discrimination and social disapprobation. But there are other reasons to worry about such research. The very motivation for seeking an “origin” of homosexuality reveals homophobia. Moreover, such research may lead to prenatal tests that claim to predict for homosexuality. For homosexual people who live in countries with no legal protections these dangers are particularly serious. (shrink)
